It's a Philips BSF 433 A. After cleaning it I can see that the varnish on the case is in pretty bad nick but I'm ready to try and work on that.
But of course, more importantly the insides seem complete apart from the cut power cord. The EL84 tube is also cracked so I'll have to source one of those. The wax caps on the bottom no doubt need replacing too.
Tomorrow when I get my new fancy multimeter I plan to check the power transformer, measure the resistors to see if they're in spec and order replacement for all the wax and electrolytic caps. Is there something else I should look into right away?
